CROSS-REFERENCE TO RELATED APPLICATION

This application is a nonprovisional patent application that makes a priority claim to U.S. Provisional Application No. 62/966,075 filed Jan. 27, 2020, the disclosure of which is hereby incorporated by reference as if fully restated herein.

TECHNICAL FIELD

Exemplary embodiments of the present invention relate generally to methods for transmitting medical alerts directly to an emergency dispatch office by using a cellular device that includes a limited use SIM card.

BACKGROUND

Personal emergency response systems (PERS) are commonly employed to provide a measure of safety and security to their users. PERS typically include a communication device and a subscription to a monitoring plan. By paying for the subscription, usually on a monthly or annual basis, the subscriber may utilize the communication device to transmit a medical alert to a remote monitoring station in the event the subscriber is in need of medical attention. The monitoring station, which is commonly owned and operated by the company administering the subscription plan, will then assess the nature of the user's medical alert and, if the personnel at the monitoring station decides to do so, may forward the medical alert to an appropriate responder. In many cases, the monitoring station will forward the medical alert to a local government operated emergency dispatch center, which is the same responder the subscriber would have reached if the subscriber had simply called 9-1-1. In this sense, the monitoring station exists as an intermediary between the subscriber and the responder. Those skilled in the art will appreciate that in dire situations, having to go through an intermediary could cost precious time that may be critical to the subscriber. What's more, the cost of the subscription for the PERS can often be prohibitively high for many of those who need it most. Considered amongst these people may include, for example, the elderly and the infirm. Many of which may be on low- or fixed-incomes, if at all. Further, it is contemplated that the shortcomings of existing PERS will become more apparent given the continuously rising population of elderly persons worldwide. In the United States alone, there are approx. 50 million seniors (aged 65 and older) and this number is projected to grow to approx. 90 million by 2050.

The communication devices used in PERS generally come in two varieties—wired and mobile. The wired communication devices typically include a transmitter worn by the subscriber that can be used to transmit a signal (e.g., by way of radio frequency, WIFI, Bluetooth, etc.) to a receiver installed in the subscriber's home (or elsewhere). Upon receiving the signal, the receiver may then transmit a medical alert over a landline. Those skilled in the art will appreciate, however, that this functionality is dependent upon either a close proximity to the receiver or the availability of WIFI. In many instances in which the subscriber would actually need the PERS, this may be inadequate. Mobile communication devices, in contrast, may offer greater range by operating over cellular networks, but are often more costly because the subscriber may be required to continuously pay for a cellular plan (which may be included in the cost of the subscription plan). App-based solutions also exist, but are only available to subscribers who possess smartphones, which only further adds to the overall cost.

Accordingly, those skilled in the art continue with research and development efforts in the field of personal emergency response systems.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

The following detailed description refers to the accompanying drawings, which illustrate specific examples described by the disclosure. Other examples having different structures and operations do not depart from the scope of the present disclosure. Like reference numerals may refer to the same feature, element, or component in the different drawings.

Illustrative, non-exhaustive examples, which may be, but are not necessarily, claimed, of the subject matter according the present disclosure are provided below. Reference herein to “example” means that one or more feature, structure, element, component, characteristic and/or operational step described in connection with the example is included in at least one embodiment and/or implementation of the subject matter according to the present disclosure. Thus, the phrase “an example” and similar language throughout the present disclosure may, but do not necessarily, refer to the same example. Further, the subject matter characterizing any one example may, but does not necessarily, include the subject matter characterizing any other example.

FIG. 1 depicts an existing system 10 for transmitting a medical alert to an emergency dispatch office 24. The system 10 includes a wired PERS 14, a landline 20, a subscriber 12 to a monitoring plan (usually sold to the subscriber as a monthly and/or annual fee), a monitoring center 22, and an emergency dispatch office 24. The wired PERS 14 may include a transmitter 16 kept on the person of the subscriber 12 and a receiver 18 configured to transmit medical alerts over the landline 20. In the event the subscriber 12 is in need of medical attention, the subscriber 12 may use the PERS 14 to transmit (e.g., by way of radio frequency, WIFI, Bluetooth, etc.) a medical alert (e.g., phone calls, voice messages, and/or text messages) to the monitoring center 22. In many cases, the monitoring center 22 is owned and operated by the monitoring company administering the monitoring plan. Upon receiving the medical alert, the monitoring center 22 may then assess the nature the medical alert and direct the medical alert to an emergency dispatch office 24. The emergency dispatch office 24 may then dispatch an appropriate emergency response to the user 12. Notably, the receiver 18 is an intermediary device between the transmitter 16 and the landline 20, and the monitoring center 22 is an intermediary between the subscriber 12 and the emergency dispatch office 24.

FIG. 2 depicts another existing system 30 for transmitting a medical alert to an emergency dispatch office 42. This system 30 is similar to the system 10 of FIG. 1 in that it also includes a monitoring center 40 and a subscriber 32 to a monitoring plan. However, the PERS 34 of this system 30 transmits the medical alert over a cellular network 38 instead of a landline 20, and the subscriber 32 is provided with a cellular device 36 instead of a transmitter 16 and receiver 18. The subscriber 32 may, when in need, use the cellular device 36 to transmit a medical alert to the monitoring center 40 (still existing as an intermediary) which can then forward the medical alert to an emergency dispatch office 42.

Examples of PERS, like the ones depicted in FIGS. 1 and 2, include: Lively Mobile, available from GreatCall, Inc., of Del Mar, Calif.; Life Alert, available from Life Alert Emergency Response, Inc., of Los Angeles, Calif.; LifeStation, available from LifeStation, Inc., of Union, N.J., and others.

The present disclosure provides embodiments of methods and devices for transmitting a medical alert directly to an emergency dispatch office. It is contemplated that the methods may present improvements over the existing systems described above by eliminating the need for intermediaries (e.g., the monitoring center) and intermediary devices (e.g., receiver), while also significantly lowering the cost transmitting a medical alert to an emergency dispatch center. The device of the present disclosure is a cellular device that typifies the sort of cellular device that may be employed by the methods. While the embodiments described herein are exemplary, they are not meant to be limiting.

FIG. 3 depicts a cellular device 50 (herein, the “device”) that may be utilized to establish a communication link over a cellular network so that a user may transmit a medical alert directly to an emergency dispatch office. As shown, the device 50 may include a small, generally rectangular body 52 that defines various sides (i.e., front, back, left, right, top, and bottom). The body 52 may be fabricated out of any suitable material, including polymeric and metallic materials, and may include any suitable configuration of seals, fasteners, and the like to securely house the internal components therein (e.g., within an interior space defined by the body). While the device 50 itself may be fabricated in different sizes and shapes (e.g., circular, rounded, and/or irregular shapes), it is contemplated that the rectangular design may be preferred because the various sides can provide for components/features that enable the user to interface with the device 50, and the small size may be preferred because it lends to the overall portability of the device 50. Ideally, the device 50 may be lightweight and easy to use with one hand.

In one or more embodiments, the body 50 may be coupled to a wearable feature to help keep the device on the user's person. For example, the device 50 may be fixedly connected to a lanyard so that the user may wear the device 50 like a pendant. In another example, the device 50 may be fixedly connected to a watch strap so that the user may wear the device 50 on his/her wrist. In yet another example, the device 50 may be releasably connected to a belt clip so that the user may wear the device 50 on his/her waist. Those skilled in the art will appreciate that various other wearable features may be employed without departing from the scope of the present disclosure.

Preferably, the device 50 may be designed with a simplified interface so that the user may quickly select a desired call recipient and initiate a call without much navigation on the device. As shown, the front side of the device 50 may be provided with an electronic display screen 54, a plurality of call buttons 60, a speaker 56, and a microphone 58. Collectively, these features may enable the user to interface with the device 50 when placing and/or receiving a call. Each call button 60 may be configured to initiate a call to a predetermined call recipient when the call button 60 is actuated by a user (e.g., physically depresses the button). While physically depressible buttons are shown, those skilled in the art will appreciate that touchscreen displays may also be employed without departing from the scope of the present disclosure. A touchscreen display may present actuatable call buttons in the same or in a substantially similar arrangement as the arrangement of call buttons 60 shown. The speaker 56 and the microphone 58 enable the device 50 to receive and broadcast communications, while information about the call may be displayed on the electronic display screen 54.

The display screen 54 may include any suitable type of electronic display screen, such as light-emitting diode displays (LED) and/or liquid crystal displays (LCD), and may be sized and shaped as desired. Typical—but useful—information that may be presented on the display screen 54 can include, for example, device settings (e.g., volume, battery level, wireless connection status, control panels), programmed information (e.g., time, date, contact information), call information (e.g., recipient, caller identity, call duration, missed calls), text messages and the like. In the configuration shown, the display screen 54 may be centered along the width of the device 50 and biased towards the top.

The speaker 56 and the microphone 58 may be centered along the width of the device 50, with the speaker 56 being biased towards the top above display screen 54, and the microphone 58 being biased towards the bottom below the emergency call button 62. Like the display screen 54, any suitable speaker and/or microphone may be employed, such as the commercially available speakers and microphones typically used in common cell phones. Preferably, the size and performance of the speaker 56 and the microphone 58 would enable the user to hear and speak while using the device 50 from a distance of at least, for example, about 4 to 18 inches away.

The plurality of call buttons 60 may include an emergency call button 62 and two secondary call buttons 64. The emergency call button 62 may be centered along the width of the device 50 and biased towards the bottom. The two secondary call buttons 64 may generally be smaller and disposed to the upper left and the upper right of the emergency call button 62. In a preferred embodiment, upon being pressed, the emergency call button 62 may initiate a 9-1-1 call to an emergency dispatch office (e.g., local government operated, private emergency response, etc.), whereas the secondary call button 64 may initiate a call to a predetermined call recipient of the user's choice. Those skilled in the art will appreciate that by pre-programming the emergency call button 62 to directly call an emergency dispatch office (e.g., by dialing 9-1-1), the device 50 may effectively eliminate the need for an intermediary (i.e., monitoring station) between the user and the emergency dispatch office, thereby saving precious time that may be critical to the user. The predetermined call recipient for the secondary call buttons 64 may be, for example, a family member (e.g., a parent), a neighbor, a social worker, a home health aide, a nurse, a doctor, etc. Thus, by providing an emergency call button 62 and secondary call buttons 64, a user of the device 50 may thereby choose an appropriate call recipient based on situational considerations such as, for example, the severity of the user's injuries, the relative closeness (by geographic location) of the potential call recipients, and the like. Those skilled in the art will appreciate that other call button arrangements (including arrangements with either more or less emergency and/or secondary call buttons, arrangements with other types of call buttons, and/or arrangements with the buttons in different locations) may also be utilized.

In one or more embodiments, the device 50 may also be configured to accept incoming calls. Towards this end, the plurality of call buttons 60 may provide for a call button 60 that is configured to accept the call upon being pressed. For example, a secondary call button 64 may be designated for this purpose. Additionally, or alternatively, a dedicated call button may be provided to accept incoming calls. Various other configurations are possible. Further, the device 50 may also be programmed to selectively filter calls such that only calls from pre-designated callers may be accepted (e.g., the call recipients associated with the emergency call button 62 and/or either of the secondary call buttons 64). This functionality may prevent the receipt of unwanted calls (e.g., unsolicited marketing).

Referring to FIGS. 4 and 5, the device 50 may also include a power switch 66 and a pair of up-down directional buttons 68. These buttons 66, 68 may be employed to provide a quick, tactile way of receiving user input. For example, the power switch 66 may be utilized to turn the device 50 on/off, whereas the directional buttons 68 may be used for navigating the user interface (e.g., adjusting volume, scrolling through contact information, etc.). The device 50 may also include a variety of generally useful features such as a radio 70 (FIG. 8) and a flashlight 72 (FIG. 6). A radio 70 included in the device 50 may be configured to receive broadcast signals (e.g., AM and/or FM) in conjunction with the wireless communication module 88 or as a dedicated module. Beyond enjoying music and talk radio, it is contemplated that the radio 70 may enable the user to tune into emergency advisory radio stations as a backup to the call functionality of the device 50 in the event of an electrical blackout or a cellular network failure. In a similar sense, a flashlight 72 may be included to illuminate the user's surroundings in emergency situations, or otherwise as needed. As shown, the right and left sides of the device body 52 may include on/off toggle switches 74, 76 for the radio 70 and the flashlight 72 for quick access. Collectively, these features ensure that the user is not “kept in the dark.”

Referring to FIG. 7, the I/O (i.e., input/output) of the device 50 may include a port 78 and phone connector 80 (i.e., headphone jack). Port 78 may utilize any suitable type of connection (e.g., micro USB, USB C, etc.) and may be utilized to charge the device 50 and/or transfer data. An appropriate cable may be provided to establish a connection therefrom. Phone connector 80 enables the user to plug in headphones and may be provided in a variety of sizes (e.g., standard 2.5 mm, 2.5 mm, and 6.35 mm variants).

Referring now to FIG. 8, the device 50 may function by way of a microprocessor 82, data store 84, battery 86, and wireless communication module 88 (e.g., transceiver). The microprocessor 82 may include any processor or combination of processors capable of performing the functions described by this disclosure. A suitable data store 84 may be selected based on, among other things, the memory requirements of the device components and the amount of data a user is likely to provide. Battery 86 can be any one or more batteries capable of powering the device, including rechargeable and/or traditional single use batteries. It is contemplated that component and programming solutions will be apparent to those of ordinary skill in the art.

The wireless communication module 88 may connect to a wireless network and attempt to establish a communication link with a call recipient (e.g., by dialing a phone number). Upon doing so, the user may thereby transmit and receive messages (e.g., text messages and/or voice audio) to and from the call recipient. The communication link may be established over any suitable wireless network including cellular phone networks, such as the networks operated by mobile phone service providers (e.g., Verizon, AT&T, Sprint, T-Mobile, etc.), as well as over broadband internet (e.g., voice over internet protocol, by way of WIFI). The wireless communication module 88 may include, for example, an antenna and a receiver, or a transceiver that integrates the two functions. These components are generally commercially available, the suitability of which will be apparent to those of ordinary skill in the art.

Referring back to FIG. 6, the device may include a reader 90 that a user may insert a subscriber identity module identification card (SIM card) into. SIM cards are used to identify and authenticate users of mobile telephony devices. By inserting a SIM card into the reader 90, the device may be enabled to connect to a cellular network. Those skilled in the art will appreciate that various SIM cards may be provided with a range of features (e.g., text messaging, minutes for calling, data, etc.) depending on the plan associated with the SIM card. Some SIM cards may be configured to provide for the full range of features (e.g., unlimited call/text/data) but generally require a continuing subscription to a cellular plan. Other SIM cards may be more limited in features (e.g., a predetermined number of minutes and texting, no data) but can be purchased with a smaller one-time fee. In one embodiment, the device 50 may be provided with a limited-use SIM card 92 that only allows emergency calls. Such a SIM card 92 may enable the device 50 to place a call to an emergency dispatch office when the user presses the emergency call button 62. In a more preferred embodiment, the limited-use SIM card 92 may also provide for a limited number of calls (expiring thereafter), thereby enabling the secondary call buttons 64 to place calls to predetermined call recipients.

Preferably, the device 50 may also include a tracking system 94 for determining the location of the user. The tracking system 94 may include a dedicated module (e.g., transceiver) or may be provided for in conjunction with the wireless communication module 88. The tracking system 94 may track the user's location by way of a global positioning system 96 (GPS) or a custom geolocation system focusing on local terrain. In practice, the tracking system 94 may transmit the user's location to the call recipient when the user presses a call button 60. Those skilled in the art will appreciate that there may be instances where the user is not able to verbally communicate his/her location (e.g., perhaps the user does not know or due to physical inability). For at least this reason, a non-verbal way of transmitting one's location would find utility.

Optionally, the device may also be provided with a fall detector 98. This fall detector may include any suitable type of sensor such as, but not limited to, accelerometers, impact sensors, combinations thereof, and/or the like. It is contemplated that the device 50 may be configured such that when the user experiences a fall, the fall detector 98 may detect the occurrence of the fall (e.g., commensurate with a threshold level of acceleration or impact), and the device 50 may automatically initiate a call or transmit a message (e.g., a prerecorded voice and/or text message) to the appropriate recipient. If a tracking system 94 is provided, the device 50 may also transmit the user's location to the recipient as well.

FIG. 9 is a flow diagram of a method 100 for enabling a user to transmit a medical alert. Referring to block 110, the method 100 may begin by providing a cellular device (such as the device 50 of FIGS. 3-8) that is configured to initiate a call over existing cellular networks. By this functionality, it is contemplated that neither call forwarding functionality nor an intermediary device is required to transmit a medical alert. The cellular device may be provided with a SIM card reader and the basic components for cellular functionality (e.g., transmitter, receiver, microprocessor, battery, data store, microphone, speaker, etc.). Further, the cellular device may also include a user interface comprising buttons (e.g., physically depressible button and/or buttons on a touchscreen) that enable the user to interface with the cellular device. In preferred embodiments, the device may also be provided with a fall detector and/or a tracking system.

Referring to block 120, the method 100 may include providing a limited use SIM card that is insertable into the cellular device. The limited use SIM card may be configured to only permit emergency calls, or may be preloaded with a limited number of calls and/or text (expiring thereafter). It is contemplated that the limited use SIM card would not require the user to pay monthly fees, nor subscribe to a continuing cell phone plan. Preferably, the limited use SIM card would be as inexpensive as possible, with the initial cost of the SIM card being one of the few expenses, if not the only expense, for call functionality. The user may insert this limited use SIM card into the cellular device by way of the SIM card reader.

Referring to block 130, the method 100 includes providing user interface software on the device that is configured to enable users to, among other things, access the various features of the device such as the buttons, speaker, and microphone. Doing so may enable the user to save phone numbers onto the data store. These phone numbers may be retrieved by the microprocessor in the event the user is in need of medical attention (described in greater detail below). Further, by this software, the user may also preemptively record and save voice and/or text messages onto the data store that may be transmitted when needed (also described below).

Referring to block 140, the method 100 may include the optional step of preloading, onto the data store, phone numbers associated with specific call recipients. Phone numbers that may be preloaded may include, for example, the phone number for local emergency dispatch offices, specific emergency responders, police stations, medical centers, and the like. In one or more embodiments, appropriate phone numbers may be selected based on the location and/or preferences of the user, resulting in a device that has been customized for the needs of said user.

Referring to block 150, the method 100 includes providing call initiation software on the device that is configured to associate a phone number of a predetermined call recipient with a button provided on the device, and to initiate a call to the call recipient when the user presses the button. The association between the phone number and the button may be programmed by the user prior to the user pressing the button. In embodiments where multiple buttons are provided, the software may be configured to associate different phone numbers with each of the buttons such that a variety of call options is available to the user. In effect, when the user presses one of the buttons, the software may be executed by the microprocessor to retrieve a phone number from the data store and connect to a cellular network. The call initiation software may then establish a communication link with the associated call recipient over the cellular network by dialing the phone number. Preferably, at least one of the phone numbers associated with a button by the call initiation software may be the phone number of an emergency dispatch office and/or 9-1-1. The user may press this button in the event the user is in need of emergency medical attention. The other buttons, if provided, may be associated with neighbors, family members, local medical response offices, and the like, which may be appropriate for instances in which the user is in need of medical attention, but not severe enough to qualify as an emergency. Upon establishing the communication link, the user may then verbally communicate information about the user's medication, condition, location, and/or other information as appropriate to enable the call recipient to respond to the user's need for medical attention. It is contemplated that by this software, the user may be enabled to quickly and easily request medical assistance, emergency or otherwise, without much navigation on the user interface of the device. Further, those skilled in the art will appreciate that block 150 may, in effect, eliminate the need for an intermediary (e.g., monitoring center) between an emergency response dispatch office and the user, thereby saving precious time that may be critical to the user.

Referring to block 160, if the device is provided with a fall detector, the method 100 may include the optional step of providing fall detection software on the device that is configured to automatically initiate a call when the device detects a fall by the user. More specifically, when the device detects a fall, this software may be executed by the microprocessor to retrieve a phone number from the data store and connect to a cellular network. The fall detection software may then establish a communication link with the associated call recipient over a cellular network by dialing the phone number. The phone number may, but need not, be the phone number of an emergency dispatch office and/or 9-1-1. In any case, those skilled in the art will appreciate that block 160 enables the user to transmit a medical alert directly to a call recipient even if the user is incapacitated by the fall, as often occurs with the elderly or infirm.

Referring to block 170, the method 100 may include the step of providing automated messaging software on the device. The automated messaging software may be provided either additionally or alternatively to the call initiation software and the fall detection software. When a call is initiated (e.g., when a button is pressed or a fall is detected), the automated messaging software may be executed by the microprocessor to retrieve a prerecorded message from the data store (e.g., a voice message or a text message). The automated messaging software may then connect to a cellular network and establish a communication link with a call recipient (if not done so already). The automated messaging software can then automatically transmit the prerecorded message to the call recipient over the cellular network. It is contemplated that this functionally may be desirable for users who, for one reason or another, are unable to speak into the device.

Referring to block 180, if the device is provided with a tracking system, the method 100 may also include the optional step of providing location tracking software on the device that is configured to automatically transmit the user's location when a call is initiated. This may include instances when, for example, the call initiation software, the fall detection software, and/or the automated messaging software is executed by the microprocessor. Upon being executed by the microprocessor, the location tracking software may retrieve the user's location from the tracking system and transmit it to the call recipient over a cellular network when a communication link is established.

Referring to block 190, the method 100 may conclude by distributing the device to a user.

FIG. 10 is a flow diagram of a method 200 for transmitting a medical alert. Referring to block 210, the method 200 may begin by providing a cellular device (such as the device of FIGS. 3-8) that is configured to initiate a call over existing cellular networks. By this functionality, it is contemplated that neither call forwarding functionality nor an intermediary device is required to transmit a medical alert. The cellular device may be provided with a SIM card reader and the basic components for cellular functionality (e.g., transmitter, receiver, microprocessor, battery, data store, microphone, speaker, etc.). Further, the cellular device may also include a user interface comprising buttons (e.g., physically depressible button and/or buttons on a touchscreen) that enable the user to interface with the cellular device. In preferred embodiments, the device may also be provided with a fall detector and/or a tracking system.

Referring to block 220, the method 200 may include inserting a limited use SIM card into the cellular device. The limited use SIM card may be configured to only permit emergency calls, or may be preloaded with a limited number of calls and/or text (expiring thereafter). It is contemplated that the limited use SIM card would not require the user to pay monthly fees, nor subscribe to a continuing cell phone plan. Preferably, the limited use SIM card would be as inexpensive as possible, with the initial cost of the SIM card being one of the few expenses, if not the only expense, for call functionality. The user may insert this limited use SIM card into the cellular device by way of the SIM card reader.

Referring to blocks 230 and 240, the phone number associated with at least one call recipient may be saved onto the device (e.g., on the data store). Of these phone numbers, at least one may then be associated with a button provided on the user interface of the device. If multiple buttons are provided on the device, different phone numbers may be associated with each of the buttons. In a preferred embodiment, one of these buttons may be associated with the phone number of a local emergency dispatch office. The other buttons may be associated with, for example, the phone numbers for a specific emergency responder, a police station, a guardian of the user, a family member, a social worker, etc. It is contemplated that by associating a button with an emergency response call recipient (e.g., emergency dispatch office) and another button with a non-emergency call recipient (e.g., a family member or neighbor), a user of the cellular device may thereby choose an appropriate call recipient based on situational considerations such as, for example, the severity of the user's injuries, the relative closeness (by geographic location) of the potential call recipients, and the like.

Referring to blocks 250 and 260, the device may then attempt to connect to a cellular network and establish a communication link. Connecting to a cellular network may entail, for example, pressing one or more of the buttons on the device to initiate the execution of preprogrammed software causing the device to connect to a cellular network based on the functionality provided by the limited use SIM card. Additionally, or alternatively, the execution of the preprogrammed software may be initiated by a fall detector provided on the cellular device when it detects a fall. In any case, once connected, the device may thereby attempt to establish a communication link with a call recipient by dialing the phone number.

Referring to block 270, the method 200 may optionally include transmitting the user's location to the call recipient over the cellular network. This functionality may be provided by the execution of preprogrammed software causing the device to retrieve the user's location from a tracking system and to transmit the user's location to the call recipient when a call is initiated.
